session and errors detected by VERICUT SessionSession 2 2 TypicalTypical VERICUTVERICUT SessionSession NCNC 文件 文件 This session demonstrates how to setup VERICUT for processing a tool path file In order to simulate the cutting action of a tool path the following actions must be performed 1 Define the size shape and location of the stock to be machined 2 Specify a tool path file to be processed by VERICUT and locate its origin 3 Indicate how tool descriptions will be supplied The typical usage of VERICUT consists of opening a startup User file that contains all the 1 machine tool and 2 control configuration information All that needs to be changed is the job specific informations like Stock program file and cutting tool information SessionSession Steps Steps 1 1 StartStart fromfrom

CLSCLS 文件 文件 This session demonstrates how to define and position simple parametric models to represent a job setup in a Workpiece view In this type of verification environment you must then achieve the desired relationship between the workpiece setup and the tool path coordinate system to simulate the cutting action This can be done by either moving the tool path coordinate system relative to the stock model or moving the stock model relative to the tool path coordinate system the affect in a Workpiece view is the same This session will demonstrate how to move the models The step at the end of the session shows how to save the session configuration in a User file so VERICUT can be quickly and easily configured to re process the tool path file SessionSession Steps Steps 1 1 StartStart
